DIVERTER FOR FLUID STREAMS.

To all whom it may comermfl:

Be it known that I, GEORG J. HENR J r., a citizen of the United St ates,"residing at San Francisco, county of San Francisco,

State of California, have invented a new and useful Diverter for Fluid Streams, of which the following is a specification.

Heretofore, it has been customary in operating tangential wheels under fluid, wa-

ter or gas pressure issuing from a nozzle in the sform of a jet against the buckets of said wheels, to regulate the amountof fluid impinging upon the buckets of said wheels by deflecting a greater or less quantity'of pressure fluid from the buckets, either by swinging the nozzle from which the water or fluid issues on a pivotal joint so that the stream would come partially or wholly within the range of said buckets and impinge thereon to meet the requirements of the load on the motor wheel at diiferent times, or to interpose after the fluid jet had issued from the stationary'nozzle, a deflector or plate which can be swung. more or less into the issuing jet before it reaches the buckets of the motor wheel, said plate defleeting from the buckets agreater or less quantity of the issuing fluid-jet. Sucha device in its general form is well known to the art, and is the subject of a previous patent issued to the writer, and as such is not claimed broadly in the present'invention,

but in hydro ele'ctric practice, the power being developed by these wheels is :frequently very great and the fluid or water. pressure issues under a high head, so that the use of a plate for deflecting the jet of water from its ,norlnal path causes a great turning moment aboutthe axis on which the deflector may be pivoted 'Suchturning moment must be overcome by the governor or by the device actuated by hand to shift the deflector partially or wholly into or outof the-jet. To counteraetthis turning moment, the: plate is usually given a curved shape, as set forth in my'latent No. 853,787.

issued May 14th 1907. It is obviousthat in order to accomplish the desired result it is only necessary 'to divert the jet or portions of the jet through a comparatively small distance in order that the deflectedgordr verted water shouldclear the buckets :of the wheel.

wheel, abdisturbance of the otherwise deadv waterinthe tailrace takes place, interfering with the normal clearing of the tail race by gravity action on the, water, and sometimes ,pilin the water up to, a considerable degree." i Water so deflectedzinto the wheel pit causes a considerable noise and some {times even a vibration of the foundations and machinery; these objections'enabling the jet of issuing water or other fluid to be partially or wholly diverted from .itsynormal' path so My diverter overcomes thatsuch diverted water or fluid'willrclear the buckets ofthe motor wheel and at the j 1 same timeits general direction will not be changed-except .toasinalldegree, thus en-' .abli'ng'the water to discharge outward in the same general directio'nthrough the 0 end portion of the tail race without inter er ing with the water flowing through the tail race that hasbeen utilized and discharged from the buckets of the motor wheel.

In order to accomplishthe rounterbalana ing of the turning moment I utilize two,

plates so related that the diverted water after passing over the surface ,ofone plate is received upon thesurface, of the second plate and diverted back againinto a path approximately parallel with its original directicn, and where desired, it may, over the surface of yone or both ot- :these plates, be

given a sidewise direction into two or more elements, and the surfaces of the plates may be-so shapedl'thatthe water may be forced their supporting members or may. beseparate and boltedzthereto, if the fluid has any corrosive or. erosive action upon the mate'- rial used in, their structure, making it advisable to replace them-without replacing lthesupporting members, but in ordinary practice Iprefer to cast these plates integral' with the supporting members. By referring to the accompanying drawing the form of mv improved diverter and its-action will be better understood. I v

Figure 1 illustratesthe principle involved ;in my diverter and counterbalancing of the v device. Fig 2 is a cross section. through one of. thepreferredi fbnmsof diverters 1ll'ustrating the curved paths over which. the diverted jet passes,.with the water wheel and nozzle in their usual positions. Fig. 3 is a plan view of Fig. 2. Fig. 4 is a perspective view with one of the side supporting plates. removed. Fig, 5 is an end view showing.

the path of the diverted water where it is desired to divide it into twoportions and fan it out as it is being discharged from the diverter surface.

The same letters. illustrate similar parts surface B byv which. itflis again turned into its direction. B substantiallyparallel with itsientry direction A.

Plates A andz-B are mounted uponor cast integral with side supporting plates G and,

D whicli. in turn are mounted upon an appnopriate axis. E which is provided with suitable levers and: connections of Well. known: form to swing: the diverter formed of plates A. B. C. andD; about the axis Emore or lesswholly into: or out of' the issuing jet A @n thejet being first received upon the plate A and; being diverted thereby. from its original direction,.there is a turning moment produced about the axis E tending to swing theplate about said: axis E in the direction F, and. upon. the water "acting upon the plateB there is a turning moment produced about the sameiaxis E tending toswing the diverter in: the direction Gr.

showsthe water wheel'andK the nozzle.

Itwilli be noticed that. these turning moments are opposite in direction and as the platestAi. and. B. receive the same quantities of pressure fluid, andturn ,said; pressure fluidithrough approximately the same angle,

said'turning moments F. and G. will be substantially equal in. magnitude. -They will therefore counterbalance each othermaking the movement of the diverter .plate wholly or partially into or out ofv thefluid jet,iwith a very; much. lighter. load; upon the mechanism for shifting it and. therefore enabling the station attendant to easily swing the plate. on the automatic governor to easily swing the plate as may be required to com-. In practice the shaft upon which the diverter ismounted is, connected: to any manual or automaticactw.

ating device. Moreover;. the fluid discharged; inthe direction: B will clear the buckets of the'moton wheel and. discharge freely into the; tail:- race without disturbance in the wheel: pit, and without impact on; any of. the deadwater discharged fromthe buck -ets of the wheel, thus preventing-vibration of the; machinery and: foundations, andi disturbance of the tail water which have been .obj ectionable features in deflectors heretofore.

'llhedischarge surface B I prefer to make .partially flattened on its sides and to raise it somewhat in the center as indicated by H- in Figs. 4 and 5. This raised portion acts =uponthe water flowing over the surface of the plate B in the same manner as the wedge or splitter in the well known tangential: wheel bucket, dividing the flowing water into-two or more portions so that it takeson a side directi'on. Any stresses introduced into the parts are counterbalanced by these two portions which are diverted equally and opposit'e to'each other indirection fro the normal path.

Having thus described my divert'er, I claim:- a 1. In a deflector for. fluid streams aprimarysurface for receiving a fluidjet and changing the direction offlow of'the fl'uid whilepassing over said surface in combinar tlon w1th-asecondar'y surface for'recelvmg said fluid after ltSPflSSELgBGW-BI the primary" surface and partially or wholly returning the -direction of flow to that of'the fluid jet. 2.
